The Broncos will be without three starters in their rematch with the Chargers on Sunday.
In addition to the loss of running back C.J. Anderson (knee, injured reserve), inside linebacker Brandon Marshall (hamstring) and cornerback Aqib Talib (back) are sidelined with injuries.
Marshall was limited in practice Friday after injuring his hamstring last Monday against Houston and did not make enough progress in his recovery to warrant playing Sunday. Nor did Talib, apparently, whose low-back pain kept him out of two day practices last week and limited him Friday.
Starting in their place are linebacker Corey Nelson and cornerback Bradley Roby, respectively.
